OFT300 (Vortech/OFT) help needed (tune issue)

[sirsol66]

Running out of ideas for trouble shooting so decided to put up a post about this. I have a couple e-mails out to OpenFlash with data logs but no reply yet and the car is my daily, so any help is greatly appreciated.

Setup:
2014 FR-S
Vortech SC (standard pulley)
OFT
OFH (Tune provided by Vishnu)
Vortech maxFlow BOV

Install of the kit went smoothly and took about 1 day.

Car runs and drive just fine, builds power, and runs great at WOT. The car is showing very, very high fuel trims however (25+).

What has been confirmed:
Exhaust leak checked (all connections checked by hand and fog test)
Intake side leak checked (all connections checked by soapy water test while pressurized and also by MAF cleaner when at idle)

Logs:
Drive around with some WOT:

Drive around with no WOT, just city driving and sustained cruise:

Things to note:
-OFT at idle showed "boost ~ -10 psi", "MAP ~ 4.5psi" so I thought I had a vaccum leak. I hooked up a manual boost gauge though and confirmed ~20 in of vacuum. Is this a sign of a bad MAP sensor or something else? I havent really looked at this parameters before in detail so I am not sure what's "normal"
*update: I put on my engineering pants and realized that 10 psi at idle amounts to right around 20 inches of mercury for vacuum, so we're good there. MAP sensor seems to be measuring okay.*

-Anyone with the maxflow BOV and Shiv's off the shelf tune? This BOV seems to move a lot more air than the standard BPV the kit comes with so I'm wondering if its contributing. I may try swapping it out to the standard BOV to see what happens.
*update: Swapped out the maxflow for the standard BOV+pipe that comes with the kit. No impact. Log as follows:

Any help is GREATLY appreciated! $20 paypal to anyone that can help me figure this out!

Well one thing ruled out. I put on my engineering pants and realized that 10 psi at idle amounts to right around 20 inches of mercury for vacuum, so we're good there. MAP sensor seems to be measuring okay. Any thoughts?

Its unlikely to be tune issue ,it most likely hardware problem

You are using the correct map sensor required for the tune ?

if my memory is correct it was 2.5 bar omni , if you using anything else it will need changes to tune.

Is your maf sensor clean, ie no oil from filter on it etc

MAP sensor is the 2.5 bar omni that comes with the kit.

The MAF sensor was taken out of the stock intake pipe and moved over. No chance of there being oil on it. Tonight I'm going to swap MAF's between my two cars to see if that fixes it just in case.

Any other ideas? Thanks for the suggestion Steve.

There's been absolutely zero reply from openflash...Calling them now.

How familiar are you with RomRaider? Could dig into the tune yourself and look for something amiss. I'd be glad to help.

[Yobiwan]

can you send me a bin file you using, yobiwan@gmail.com
I ll check with mine.

Sadly not familiar with RomRaider at all.

I did get a hold of Vishnu yesterday; he said the tune looks safe and requested a few additional logs to get the idle tuned in.

I'll keep this updated. Some pre tune logs if anyone is interested:
